Hi, I’m Mariko, living in Whanganui, New Zealand, and passionate about making sustainable living simple and joyful. My focus is Kiero, a smart and eco-friendly composting system that turns your kitchen scraps into rich, living soil.
Through Kiero, I aim to inspire people to live more sustainably, enjoy the process of turning scraps into soil, and feel the satisfaction of caring for the earth every day.
Join me in making waste a resource, and experience the joy of growing life from what we normally throw away.
